Infield Fly redux

[Tru_in_Blu]

Thanx for the replies so far.

From an older case study file I have, I found the following:

PLAY 8.2-35
With one out and R1 on 2B, R2 on 1B, B3 hits an apparent infield fly. The umpire does not call "infield fly." The fly ball is not caught and in the confusion, both R1 and R2 are tagged off base resulting in three outs.
RULING: The infield fly should have been in effect. Failure of the umpire to invoke the infield fly place the runner in jeopardy. This is correctable by calling the batter out and returning the runners to their respective bases (8-2l; 10-3C)
Has this interpretation been changed? While this case play was not identical to the OP play, it's similarity is relevant.
